Multi-Omics and Its Clinical Application in Hepatocellular Carcinoma: Current Progress and Future Opportunities.

Hepatocellular carcinoma (HCC) is the sixth most common malignancy and the fourth leading cause of cancer related death worldwide. China covers over half of cases, leading HCC to be a vital threaten to public health. Despite advances in diagnosis and treatments, high recurrence rate remains a major obstacle in HCC management.

Diet and liver cancer risk: a narrative review of epidemiological evidence.

Primary liver cancer is the third leading cause of cancer-related death worldwide. Most patients are diagnosed at late stages with poor prognosis; thus, identification of modifiable risk factors for primary prevention of liver cancer is urgently needed. The well-established risk factors of liver cancer include chronic infection with hepatitis B virus (HBV) or hepatitis C virus (HCV), heavy alcohol consumption, metabolic diseases such as obesity and diabetes, and aflatoxin exposure.

Comprehensive assessments of long-term sleep habits in epidemiological study: Validity and reliability of sleep factors questionnaire (SFQ) among Chinese women.

Objective: Epidemiological studies suggested that poor sleep is a potentially novel risk factor for several health outcomes currently; however, there are no validated questionnaires that can systematically measure sleep parameters within these studies. We evaluated the reliability and validity of 17-item sleep factors questionnaire (SFQ), which was developed to comprehensively assess long-term sleep habits for the Jiujiang Breast Cancer Study (JBCS), Jiujiang, China.

Methods: The participants included 100 women aged 18-74years, who were randomly selected from the JBCS project, and completed a SFQ at baseline and again 1year later, and 4 quarterly 30 consecutive days (a total of 120days) sleep diaries over this same year.

Type 2 diabetes and the risk of non-Hodgkin's lymphoma: a report from two population-based cohort studies in China.

Coinciding with the increased incidence of non-Hodgkin's lymphoma (NHL) during the past decades, there has been a significant increase in the prevalence of diabetes mellitus in mainland China. We therefore evaluated whether type 2 diabetes (T2D) is associated with the risk of NHL using data from the Shanghai Men's Health Study (SMHS) and the Shanghai Women's Health Study (SWHS). The SMHS and SWHS are two on-going, prospective, population-based cohorts of more than 130 000 Chinese adults in urban Shanghai.

An evidence-based assessment for the association between long-term exposure to outdoor air pollution and the risk of lung cancer.

Although outdoor air pollution has been identified as carcinogenic to humans, the magnitude of the relative risk (RR) and the 95% confidence interval (CI) for lung cancer in relation to outdoor air pollution remain uncertain. On a global scale, we quantified the risk of lung cancer associated with long-term exposure to outdoor air pollution using a meta-analytic approach. Relevant cohort studies from two databases (PubMed and Web of Science) through 31 May 2014 were searched, and a total of 21 cohort studies were identified in the analysis.

Pre-existing type 2 diabetes and risk of lung cancer: a report from two prospective cohort studies of 133 024 Chinese adults in urban Shanghai.

Light exposure at night, sleep duration, melatonin, and breast cancer: a dose-response analysis of observational studies.

Evidence from observational studies on light at night (LAN) exposure, sleep duration, endogenous melatonin levels, and risk for breast cancer in women is conflicting. This led us to conduct a dose-response analysis of published observational data. Pertinent studies were identified by searching Medline, Web of Science, and EMBASE through April 2013.

Sleep duration and cancer risk: a systematic review and meta-analysis of prospective studies.

To assess the risk of cancers associated with sleep duration using a meta-analysis of published cohort studies, we performed a comprehensive search using PubMed, Embase and Web of Science through October 2013. We combined hazard ratios (HRs) from individual studies using meta-analysis approaches. A random effect dose-response analysis was used to evaluate the relationship between sleep duration and cancer risk.

Tea consumption and risk of type 2 diabetes: a dose-response meta-analysis of cohort studies.

Tea consumption has inconsistently been shown to be associated with the risk of type 2 diabetes (T2D). The aim of the present study was to conduct a dose-response meta-analysis of cohort studies assessing the association between consumption of tea and risk of developing T2D. Pertinent studies were identified by searching PubMed, Web of Science and EMBASE through 31 March 2013.

Rural-urban, sex variations, and time trend of primary liver cancer incidence in China, 1988-2005.

To investigate the incidence rate of primary liver cancer (PLC) in China in recent decades. Cancer registration data from 1988 to 2005 were used to analyze the incidence trends of PLC in 11 cities and counties in China. We estimated crude, age-specific, and age-standardized incidence rates of PLC.

Cancer incidence among adolescents and young adults in urban Shanghai, 1973-2005.

Background: Lack of cancer incidence information for adolescents and young adults led us to describe incidence trends within the young population of 15 to 49 year-olds in urban Shanghai between 1973 and 2005.

Methods: During 1973 to 2005, data on 43,009 (45.8%) male and 50,828 (54.

Risk factors of hepatocellular carcinoma--current status and perspectives.

Hepatocellular carcinoma is a common disorder worldwide which ranks 5th and 7th most common cancer among men and women. In recent years, different incidence trends have been observed in various regions, but the reasons are not completely understood. However, due to the great public efforts in HCC prevention and alternation of lifestyle, the roles of some well documented risk factors played in hepatocarcinogenesis might have changed.

The role of pre-existing diabetes mellitus on hepatocellular carcinoma occurrence and prognosis: a meta-analysis of prospective cohort studies.

Background: The impact of pre-existing diabetes mellitus (DM) on hepatocellular carcinoma (HCC) occurrence and prognosis is complex and unclear. The aim of this meta-analysis is to evaluate the association between pre-existing diabetes mellitus and hepatocellular carcinoma occurrence and prognosis.

Methods: We searched PubMed, Embase and the Cochrane Library from their inception to January, 2011 for prospective epidemiological studies assessing the effect of pre-existing diabetes mellitus on hepatocellular carcinoma occurrence, mortality outcomes, cancer recurrence, and treatment-related complications.

Declining rates of hepatocellular carcinoma in urban Shanghai: incidence trends in 1976-2005.

In China, hepatocellular carcinoma (HCC) incidence rates in several registry catchment populations are amongst the highest worldwide. The incidence rates in urban Shanghai were analyzed between 1976 and 2005 to describe and interpret the time trends. Age-specific and age-standardized rates were calculated and graphically presented.

Marital status and mortality among middle age and elderly men and women in urban Shanghai.

Background: Previous studies have suggested that marital status is associated with mortality, but few studies have been conducted in China where increasing aging population and divorce rates may have major impact on health and total mortality.

Methods: We examined the association of marital status with mortality using data from the Shanghai Women's Health Study (1996-2009) and Shanghai Men's Health Study (2002-2009), two population-based cohort studies of 74,942 women aged 40-70 years and 61,500 men aged 40-74 years at the study enrollment. Deaths were identified by biennial home visits and record linkage with the vital statistics registry.

Soy intake is associated with lower lung cancer risk: results from a meta-analysis of epidemiologic studies.

Background: Although several in vitro and animal in vivo studies have suggested that soy or soy isoflavones may exert inhibitory effects on lung carcinogenesis, epidemiologic studies have reported inconclusive results on the association between soy intake and lung cancer.

Objective: The aim of this meta-analysis was to investigate whether an association exists between soy and lung cancer in epidemiologic studies.

Design: We searched PubMed, EMBASE, and the Cochrane Library from their inception to February 2011 for both case-control and cohort studies that assessed soy consumption and lung cancer risk.

Epidemiological studies of the association between tea drinking and primary liver cancer: a meta-analysis.

Many in-vitro and animal studies have provided evidence that tea has many possible anticarcinogenic mechanisms, but epidemiological evidence for the effect of tea consumption on the primary liver cancer risk remains controversial and, to date, there have been no quantitative meta-analyses reported regarding this topic. The aim of this meta-analysis is to evaluate the association between tea consumption and the risk of primary liver cancer from case-control and cohort studies. Epidemiological studies of tea consumption in relation to primary liver cancer were identified by searching MEDLINE, EMBASE, Chinese Bio-medicine Database, and Chinese Wanfang Database, from January 1979 to December 2009.
